27-year-old Addison "Heart" Heartly works for a charity organization and usually isn't easily fooled in her job.

But before an important meeting with the biggest potential donor ever, she meets one of his employees, a cute guy who seems friendly and flirts with her. Nervously chattering away, Addison explains everything she's heard about the CEO.

Daniel Jacobs is CEO of a tech company, filthy rich, attractive, deliberately single, and a tabloid favourite, much to his chagrin. His last girlfriend never misses an opportunity to be photographed with him and spread rumours about marriage. Which is absolutely ridiculous. Because women are... just a bit of fun to him!

And when he meets Addison and she doesn't recognize him, his hunting instinct awakens. Addison is mortified when Daniel reveals his identity. She wants to run away, yet she can't deny the tension in the air. She gives in, and they end up in bed together. But the next day, Addison reads in one of the gossip magazines that Daniel has marriage plans. Apparently, she was just another conquest to him. Too bad she finds out she's pregnant with his child soon after, her boss discovers it, and she quits.

Neither of them realizes how close desire and danger really are. Are their feelings worth playing with fire?
